I see that my firmware supports fax forwarding to email. http://www.support.xerox.com/support/WC5135_WC5150/support/en_US.html?objGUID=16853 indicates that my version, 21.120.52.000 is high enough to support this option. Where can I find some instructions on setting that option up? This would be a lifesaver for my office. The only walktrhoughs I can find are for the 7312. Are the directions the same? Thanks so much!
